3 days ago I was starting my lawn mower, it is one of the pull-cord types. As I was pulling the cord released quickly, I am guessing it was coiled funny, and as I was pulling full strength it let loose. I had immediate moderate pain in my shoulder. I can draw a line across the back of my shoulder around the head of the humerus where it hurts. I have been icing and applying heat for comfort.
History: Same shoulder has had a grade 2 separation and a full anterior labrum tear repaired by open bankart in Dec. 2000.
Does this sound like a sprain/strain or possibly more like a rotator?
Thanks.
